Embodiment 1

[0022] Such as Figure 1~2 As shown, a low-resistance air filter provided by the present invention includes a frame body 2 and a filter element 4, the filter element 4 is mounted on the frame body 2, the top of the frame body 2 is provided with an air inlet 1, and the frame body There is an air outlet 3 at the bottom of the bottom, and the filter element 4 includes a plurality of filter element units, each filter element unit includes two layers of filter material and a layer of coated paper separator, the coated paper separator is sandwiched between the two layers of filter material, the filter material is fluffy PP fiber, very fluffy PP fiber is used as the filter material, so that the surface of the filter element unit has a number of hairy fibers of different lengths, so that a channel imitating the nasal cavity is formed between two adjacent filter element units, forming an imitation nasal cavity Several hairy fibers in the channel have little air resistance, and at this ...

Embodiment 2

[0024] Such as Figure 1~2 As shown, a low-resistance air filter provided by the present invention includes a frame body 2 and a filter element 4, the filter element 4 is mounted on the frame body 2, the top of the frame body 2 is provided with an air inlet 1, and the frame body There is an air outlet 3 at the bottom of the bottom, and the filter element 4 includes a plurality of filter element units, each filter element unit includes two layers of filter material and a layer of coated paper separator, the coated paper separator is sandwiched between the two layers of filter material, the filter material is fluffy The PP fiber is used, and there is a hot-melt adhesive sealing layer between the frame body 2 and the filter core 4, which prevents the air entering the air filter from passing through the gap, and improves the filtration efficiency.

Embodiment 3

[0026] Such as Figure 1~2 As shown, a low-resistance air filter provided by the present invention includes a frame body 2 and a filter element 4, the filter element 4 is mounted on the frame body 2, the top of the frame body 2 is provided with an air inlet 1, and the frame body There is an air outlet 3 at the bottom of the bottom, and the filter element 4 includes a plurality of filter element units, each filter element unit includes two layers of filter material and a layer of coated paper separator, the coated paper separator is sandwiched between the two layers of filter material, the filter material is fluffy PP fiber, several protrusions and / or pits are evenly arranged on the coated paper separator, which increases the filtering area of ​​the air filter, and at the same time, the existence of several protrusions and / or pits on the coated paper separator increases It eliminates the irregularity of the imitation nasal passage, which is beneficial for the fibers to intercep...

Abstract

The invention discloses a low-resistance air filter. The low-resistance air filter comprises a frame body (2) and a filter element (4). The filter element (4) is installed on the frame body (2), an air inlet (1) is formed in the top of the frame body (2), and an air outlet (3) is formed in the bottom of the frame body (2). The filter element (4) comprises a plurality of filter element units. Each filter element unit is composed of two filter material layers and a coated paper partition plate layer, wherein the coated paper partition plate layer is sandwiched between the two filter material layers, and the filter material is made of fluffy PP fibers. The filter element (4) comprises the filter element units, each filter element unit is composed of the two filter material layers and one coated paper partition plate layer sandwiched between the two filter material layers, and the filter material is made of fluffy PP fibers; by adopting the fluffy PP fibers as the filter material, a channel imitating the nasal cavity is formed between every two adjacent filter element units, air circulating resistance is reduced, and then the filtering efficiency of the air filter is improved.

Description

technical field [0001] The invention relates to an air filter, in particular to a low-resistance air filter. Background technique [0002] High-efficiency air filters are widely used in the air conditioning of dust-free purification workshops in optical electronics, LCD liquid crystal manufacturing, biomedicine, precision instruments, beverages, PCB printing and other industries due to their high filtration efficiency and continuous use for a long time to reduce the cost of later consumables. Terminal air supply and other fields. However, in use, it is often found that the filter resistance is large and the filter efficiency is poor, so it is urgent to design a low-resistance high-efficiency air filter. Contents of the invention [0003] The purpose of the present invention is to provide a low-resistance air filter to solve the problem of high filtration resistance of the existing high-efficiency air filter. [0004] The present invention realizes through following techn...
